HIGH SPECTRAL RESOLUTION COLOR SENSOR USING NON-DISPERSIVE ELEMENTS

摘要

The invention describes a light sensor (1) comprising a filter arrangement (11), which filter arrangement (11) comprises a number of spectral filters (F1, F2, . . . , Fn) for filtering incident light (L), wherein a spectral filter (F1, F2, . . . , Fn) is realized to pass a distinct component of the incident light (L), an aperture arrangement (12) for admitting a fraction of the incident light (L), and a sensor arrangement (13) realized to collect the admitted filtered light (L′), which sensor arrangement (13) comprises an array of sensor elements (130) for generating image-related signals (S, S1, S2, . . . , Sn) and which sensor array is sub-divided into a number of regions (R1, R2, . . . , Rn), wherein a region (R1, R2, . . . , Rn) of the sensor array is allocated to a corresponding spectral filter (Fi, F2, . . . , Fn) such that an image-related signal (S) generated by a sensor element (130) of a particular region (R1, R2, . . . , Rn) comprises information pertaining to the direction of origin and/or the spectral composition of the light passed by the corresponding spectral filter (F1, F2, . . . , Fn). The invention further describes a light sensor device (10) for determining the direction of origin and/or the spectral composition of light (L) incident at the light sensor device (10), a method of collecting incident light (L), and a method of determining the direction of origin and/or the spectral composition of incident light (L).
